Mark Willis sez:
Palentier is an Open Source software that was originally created by me and a good friend (M. Stange) for processing aerial images from un-manned aerial vehicles (UAVs) like the MikroKopter. Palentier can process aerial photographs into georeferenced and scaled images which accurately reflect the location and size of objects in the real world. These images can be exported to Google Earth or to GIS software, like ArcGIS, for review and analysis.
Our current attempt is to modify the software so that it could be useable by the KAP community. Several weeks ago, I asked for help with test images and rig GPS data from fellow KAPers. You came through and we now have results from using Palentier with KAP imagery. The system was tested using data from four places (Northern England, and Northern Libya, Southern Texas, and West Virginia). All had good results and all but one (West Virginia which I don't have permission to share publicly) are shown here.
